[Mesa-dev] Error building Mesa 32 bit version on Arch Linux

[Sandeep]

Hi,

When I try to build 32 bit Mesa on Arch Linux, I get the following error:

/usr/bin/mkdir -p ../../src/glsl/glcpp
/usr/bin/mkdir -p ../../src/glsl/glcpp
  YACC     glcpp/glcpp-parse.c
  LEX      glsl_lexer.cpp

glsl_parser.cpp: In function 'int
_mesa_glsl_parse(_mesa_glsl_parse_state*)':
glsl_parser.cpp:2616:41: error: 'scanner' was not declared in this scope

This error happens even if I try building at a commit 4 weeks ago. I'm sure
I was able to get Mesa to build atleast 1-2 weeks ago. I'm not sure if this
is a recent bug introduced in Mesa code, or if it's because of some other
software like bison/lex being buggy.

glsl_parser.cpp doesn't seem to be part of the source code, I'm guessing
it's automatically generated from glsl_parser.yy as part of the build
process. Any ideas on how I can resolve this problem?
